President Trump on Thursday appointed a divisive conservative voting rights expert to spearhead the White House’s search into allegations of widespread fraud in the 2016 presidential election. The appointment of Hans von Spakovsky has reignited debate over the legitimacy of claims that include unsubstantiated accusations from Trump that “millions of people” voted illegally for Hillary Clinton. Von Spakovsky, a former Justice Department official, sparked legal battles over voting laws during the George W. Bush administration. Von Spakovsky, 58, will join the Presidential Advisory Commission on Election Integrity, though it remains unclear what role he will take. The White House’s Thursday night announcement, which included several other administration posts, did not provide further details. The announcement did not include any biographical information about von Spakovsky, either.
